The tip of my nose is still bright red after rhinoplasty 6 weeks ago. Is this normal? (photo)

A cartilage graft was placed & is like an uneven red ball. In addition to the redness, there are dents to one side of the graft & a protrusion to the other side. I was concerned about circulation, but my doctor said that the redness is normal & needs time to heal. For the area that protrudes & is more purple, he said that he could use a needle to scrape this down from the outside of the nose in an office procedure & seemed to think this was a minimal problem. I am worried about what to do next & very unhappy with this result. Is any of this normal?
